The Scarlet Pimpernel1934

Lady Marguerite Blakeney:
Oh but Percy, through me, a good, a generous man my lose his life. Oh Percy, what can I do? How can I warn him?

Percy Blakeney:
Warn him? Against what?

Lady Marguerite Blakeney:
Against the danger if he goes back to France.

Percy Blakeney:
Well, if he's the kind of lunatic I take him to be, your warning's not going to stop him.

Lady Marguerite Blakeney:
But he might be going to his death.

Percy Blakeney:
That's all the fellow lives for. Besides, he doesn't know you're in love with him.

Lady Marguerite Blakeney:
I'm not in love with him! I admire his head of wisdom, but I'm not in love with him.

Percy Blakeney:
Oh, but you are. It's a dangerous game, my dear. Falling in love with a phantom. For all you know, he might be a married man who is deeply in love with his wife.
